Abstract: PURPOSE:To enable the detection of position with higher resolution by a system wherein a linear vehicle body contacts a roller so that it rotates the roller, and the force of rotation thereof is transmitted to a rotary encoder through a belt. CONSTITUTION:A linear vehicle body 11 is driven by a linear motor 16, and a contactor 11a provided on the lower side of the vehicle body 11 contacts a roller 1A provided in a guide rail 14 so that it rotates the roller. The force of rotation of the roller 1A is transmitted to rollers 3A-3C through belts 20 and 21, and further it is transmitted to a roller 22A on a rotary encoder 22 through a belt 23.

IPC: H04N7/32
Filed: 1991-03-26
Abstract: PURPOSE: To process consecutive information signals in real time by using a decoder in a local image coding loop. CONSTITUTION: A processor DSP 1 reads an image block to be processed from an image memory A, reads an image block corresponding to a loop stored in an image memory B and forms a difference between both blocks and gives the result to a transformation device. A DSP 2 uses an output of a cosine transformation device T to compensate a transformation coefficient to change a threshold level of the transformed coefficient and executes directly quantization Q and gives a quantized coefficient to a DSP 4. A DSP 4 executes entropy coding and forms a numeral frame. The DSP 2 executes inverse quantization Q<-1> to reproduce the coefficient and gives it to the transformation device T. The DSP 1 compensates the data from the transformation device T and uses a block subject to display and filter processing to add it to the preceding block and writes the result to the memories B, D.  A dual buffer register RT copes with the data on the coder/decoder and a transmission line.

Filed: 1981-06-03
Abstract: PURPOSE:To obtain a prescribed scanning speed through a small-sized motor by using a spring with necessary elastic force as the main driving source for a scanning mechanism, and then using the driving force of a synchronizing motor in combination. CONSTITUTION:A sample plate 2 is mounted on a scanning member 1 at a prescribed position, and the front edge 1F of the scanning member 1 is pressed in against a spring 4 as shown by an arrow (c). At this time, a moving link 9 pressed against an intermediate link 8 is displaced by 90 deg. by the free rotation of a unidirectional clutch 10 and when a microswitch operating plate 7 reaches a position 7', the roller 22R of a microswitch 22 is pressed, turning on a synchronizing motor 16. As the motor 16 rotates at a constant prescribed synchronizing speed, braking operation is performed to allow a driving pulley 11 at a prescribed pulley 11 through a timing belt 15, thus regulating the scanning speed of the scanning member 11. Since the braking force of the motor 16 is nearly equalized to the elastic force of the spring 4, the torque of the motor 16 is reduced to half.
